While this is still an active area of research, there are a few guiding principles we can draw upon to try to maximize water quality gains.

As water moves downslope in a field and encounters the prairie strips, there will be greater resistance to flow and the surface runoff water will slow down. When this water slows, some of the material it is carrying will be deposited. This generally occurs a few feet into the leading edge of the strip or immediately upslope of the strip.

Most prairie plants will not become weeds in crop fields where annual crops are grown and subjected to conventional weed management practices.

Spray drift definitely can harm the prairie strips in the first several years as the young plants are establishing, but mature prairie plants are more resilient. Mature perennial plants have deep root systems with substantial stored energy reserves, which tend to allow them to bounce back from incidental drift.

Driving on prairie strips will create disturbance and could disrupt the native plant community. Many invasive weeds are more tolerant to disturbance than prairie plants, and driving on the strips could create an environment where weeds can out-compete the prairie plants. Disturbed areas also may reduce the prairie diversity to only a few native species.

Prairie strips could serve as a source of hay if harvested later in the summer, but the plant species composition may shift. Managers may find it difficult to maintain a diversity of grass and forb species.
This is an open question for the STRIPS team, which we hope to answer soon. At least two of our farmer cooperators are planning to graze their prairie strips: one is developing a method to rotationally graze the prairie strips and another releases cattle onto his whole field after fall corn harvest. Stay tuned for research results; in the meantime, you might try it, being careful not to allow livestock to congregate in any area long enough to create bare ground.

Our cooperators are best at explaining why prairie strips are a practical farmland conservation tool. We've collected a few of their testimonials on this new web page. Check back in the future for more. Read more about Why Prairie Strips? Our Farmer & Farm Landowner Cooperators Explain
